First Results from BESIII
We present the most recent results from the BESIII experiment. This review
covers the studies of charmonium decays, light hadron spectroscopy and charm
physics. Especially, the prospects for weak decays of charm mesons are
addressed at the BESIII.Comment: Presented at Flavor Physics and CP Violation - FPCP 2010, Turin,

Finslerian dipolar modulation of the CMB power spectra at scales
A common explanation for the CMB power asymmetry is to introduce a dipolar
modulation at the stage of inflation, where the primordial power spectrum is
spatially varying. If the universe in the stage of inflation is Finslerian, and
if the Finsler spacetime is non-reversible under parity flip, ,
then a three dimensional spectrum which is the function of wave vector and
direction is valid. In this paper, a three dimensional primordial power
spectrum with preferred direction is derived in the framework of Finsler
spacetime. It is found that the amplitude of dipolar modulation is related to
the Finslerian parameter, which in turn is a function of wave vector. The
angular correlation coefficients are presented, and the numerical results for
the anisotropic correlation coefficients over the multipole range are
given.Comment: 13 pages, 1 figure, accepted by EPJ
Fully Differential Higgs Pair Production in Association With a Boson at Next-to-Next-to-Leading Order in QCD
To clarify the electroweak symmetry breaking mechanism, we need to probe the
Higgs self-couplings, which can be measured in Higgs pair productions. The
associated production with a vector boson is special due to a clear tag in the
final state. We perform a fully differential next-to-next-to-leading-order
calculation of the Higgs pair production in association with a boson at
hadron colliders, and present numerical results at the 14 TeV LHC and a future
100 TeV hadron collider.Comment: 7 pages, 7 figures, matched to the published version in PL
